if someone of the opp sex approaches me in NUS, i'd probably not like it..coz not that interested in getting to noe strangers. but i won't ignore him when he approaches me. will be friendly, but won't give him my number. i've had pple approaching me at the busstop, in the library etc, but they weren't that successful in getting to noe me. but if i'm lucky enuff to get a nice goodlooking guy approaching me, then it might be another story..hiaks
i think the best approach to knowing girls is to try to be in the same class as them, better still ask her if you can join her group for projects. since project groupmates have to exchange numbers, that's a sure way of getting her contact. but this is only if you are in the same faculty. if not, take cross-fac and pray and pray that she'll be taking that module too!
